About
Oceanic+ is a comprehensive dive computing app developed by Huish Outdoors that turns the Apple Watch Ultra into a fully featured underwater computer for divers of all experience levels. Whether you are a casual snorkeler, a passionate freediver, or a certified scuba diver, Oceanic+ covers every underwater discipline with dedicated modes, real-time data displays, and robust safety tools. The app integrates pre-dive planning with real-time water conditions, tide information, and community-sourced insights. It uses the trusted Bühlmann decompression algorithm to track nitrogen tissue loading, calculate no-decompression limits, and fire visual and haptic warnings before thresholds are crossed. Divers can configure custom gas mixes, maximum depth limits, and target dive times before descending. A social discovery layer lets users explore user-generated heatmaps to find popular dive and snorkeling spots worldwide. GPS-tracked routes are automatically logged for every snorkeling session, and an integrated media library lets you color-correct, organize, and relive underwater photos and videos. Privacy controls give you full ownership over what dive data, photos, and logbooks are shared and with whom. Additional capabilities include gear tracking from major brands, weight planning, freediving heart rate monitoring with custom alarms, seven customizable watch faces, and full dive log export. The free tier covers essential features, while advanced tools unlock with subscriptions from $1.99/month or a $129.99 annual family plan — making it practical for solo divers and dive groups alike.
